To all whom it may concern:

Be it known that we, THOMAs'DUNBAR land ETHAN I, Dones, citizens of theUnited States, residing at` Pullman, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in MetallicHopper-Cars, of which the following is a s ecil'ication. ur presentinvention concerns railway hoppercars,its princi al object being a carconstruction which sliall have strong side sills, with the weight ofthecar reduced to a minimum, at the same ti e securing a Inexi-V "b ody.To accomplish this obect, we build the car y y forming thecenter-plateportions of the sills, the'com aratively short'end beams of the sillsbeing astened thereto in any approved mariner, referably, however, bymeans of side sta esi. which form splicing means. A sill of thischaracter, due to its dee center ortion can sustainahea load `wit out unue de eetion,and buckling of the same is prevented by the side stakesattached to the sides of the body, each havin an outstanding flange. Theparts of the sill are still further strengthened and more firmly boundtogether by an angle-bar extendin substantiaily the ull length of thesill and 3c riveted to the end beams ofthe sill and to the side of thebody.

.In the accompanying drawings, which`illustrate the preferred mechanicalembodiment of our invention, metallic hopper-car. Fig. 2 is a sideeleva'- tion of the same. Fig. 3 is a vertical crosssection of the carthrough the body portion.

Fig. 4 is a ragmontany side elevation of a portion of the car, showingthe junction of one ofthe end beams with the side of the body. Fi". 5 isa horizontal cross-section on lino 5 5 oiFig. 4 looking downwardly, ondFig. 6 is a horizontal cross-section on line 6 6 of ig. 4 as viewed inthe same direction.

Supported on car-trucks 10 is a car-frame comprising, among other parts,spaced channel center sills 11 which project beyond bodybolster's l2,draft-sills 13 being secured to the projecting ends and to oud sills 14.

The car-bod includes )late sides 15, each ol which ma e made olI asingle plate or a number of pilates secured together, each side havingsecured thereto a number of upright with the sides 'of' Figure 1 is aplan view of a` side stakes 16, T-sha ed in crosssection to reventbuckling. T e ends 17 of the carodyconverge downwardly, as is shown inIg. 2, and are maintained in position by channel-struts 18, secured totheir outer faces and tocenter sills 11. Coping angleirons 19 areprovided along the top edges of `the sides and ends, having at theircorners the usual plates 20.- A. lurality of horizontal doors 21,pivoted at t Ie points 22, form the bottom of the car-body and areactuated by a numberl oi' cnains 23-passing overidlers 24 to theoperatin -windlass 25. The4 doors on the. opposite sides of the centersills 11 are 'connected by I-bearns 26, preferably tapered at their endportions, to which Lbeams the ends of chains v23 are attached, as shownin Fig. 3; Defiecting-plates 27 are secured to the webs oi the centersills 11, converging above them and riveted together alon their up er edes, while angle-bars 28 attac their en s to t e sloping ends of thecar-body. iIt should be noted that the sides are vertical for a ortionof their height and then ineline slightly upward] structure, however,present invention.

Each side sill to which the body-bolsters 12 and end sills 14 areattached comprises two end beams"29, having integral inwardl turnedflanges 30 along their upper edges, Atlife inner ends oithe Beams beingdeeper than their outer ends, as shown most clearly in Fig. y2. To theplate side 15 the inner end of each end beam is secured by means of asub-4 stantially vertical channel-stake 31 with outwardly-extendedflanges 32, which acts as a splicing-plate for the parts. Each stake 31extends to the top of the side, and that portion of cach above the endbeam 29 is connected to the adjacent sloping end 17 of the body by atapering late 33, the inner edge of which is rivetedp to the web of thestakeand the outer edge of which is flanged over at 34, Figs. 4 and 5andsecured to the end plate.' To permit end plate 17 to extend t thebotorms no part of our tom of the body, the top flange 3() teach endbeam 29 is cut away for a portion of' its length, and the lower part ofeach plate 33 is/ joined to the vertical plate portion of end beam 29 bya splice-.plate 35 on the inside/oi" the body, the same being riveted toplate d3, end beam 29, and the web of stake 31. jiielow the 11p- Thisfeature of the IOO SCT
